Hao Ren's first destination was a place called Cauldron Valley. This was a city that was sitting inside a crater left behind in the mountain ranges of the western Spirit Siphon continents. This place happened to be the hub of artifact refiners as well. The reason they choose this place to settle down was because the crater was made by a meteor.
This meteor changed the landscape and the intense heat on the impact of collision caused a lot of chemical and physical changes in the nature of the meteor. It was said that under this city there were multiple metal veins and even after hundred thousands of years, there were some veins that had yet to be discovered by the people.
Hao Ren sighed as he finished reading the book in his hand. He was sitting on the flying sword that he had refined back for time pass. The fact that even at the speed three times faster than the sound it would take him three more days to reach the Cauldron valley, it was really far from the Iron Mountain City.
